Below is a news summary of an orthopaedic research study in the Journal of Bone and Joint Surgery (JBJS), as well as the issues' full Table of Contents. A Structured, Independent Exercise Regimen Can Reduce the Need for Therapy Following Meniscus Surgery The treatment of meniscus tears in injured workers is associated with less favorable outcomes and higher utilization of clinical services. "Disability, Impairment, and Physical Therapy Utilization in Workers' Compensation Patients after Arthroscopic Partial Meniscectomy, " is a study appearing in the Journal of Bone and Joint Surgery (JBJS), which investigates the effects of a recommended, self-regulated exercise program on the number of physical therapy visits and patient outcomes. The study reviewed the success of 164 primary arthroscopic meniscectomies (the surgical procedure to remove torn areas of the two, wedge-shaped pieces of cartilage that acts as shock absorbers in the knee joint) on 155 injured workers.
For children aged 14 and under, delaying reconstructive surgery for anterior cruciate ligament (ACL) injuries may raise their risk of further injury, according to a new study by pediatric orthopaedic surgeons. If surgery occurs later than 12 weeks after the injury, the injury may even be irreparable. "Treating ACL injuries in these children is controversial, because they are still growing and the surgery has a small risk of causing a growth disturbance, " said study leader J. Todd Lawrence, M.D., Ph.D., an orthopaedic surgeon at The Children's Hospital of Philadelphia. "However, we found that the risk of additional injury outweighs the risk of growth disturbance in most children." Lawrence's study appeared in a recent issue of The American Journal of Sports Medicine. ACL injuries have increased among children and young adults in recent years, possibly because of increased participation in high-level sports such as football, skiing, lacrosse, hockey and soccer, all of which place a high demand on the knees, where the ACL is located.
An extensive study of country-specific risk of hip fracture and 10-year probability of a major fragility fracture has revealed a remarkably large geographic variation in fracture risk. Even accounting for possible errors or limitations in the source data, there was an astonishing 10-fold variation in hip fracture risk and fracture probability between countries. 'A systematic review of hip fracture incidence and probability of fracture worldwide', authored by the International Osteoporosis Foundation (IOF) Working Group on Epidemiology and Quality of Life, has been published in the journal Osteoporosis International. The aim of the study was to update the available information base on the global heterogeneity in the risk of hip fracture. Age-standardised hip fracture rates from 63 countries were compiled.
The most recent News and Numbers from the Agency for Healthcare Research and Quality reveals that in 2009, joint pain was experienced by 58% of obese adults aged 20+ in the USA and nearly 69% of extremely obese adults. In addition, researchers found that 15% of obese adults said they had diabetes, 42% reported having a heart condition, and 42% reported having high cholesterol. Among individuals classified as extremely obese (BMI of 40 or more), the percentages with diabetes or heart conditions were generally higher. BMI (Body Mass Index) is a calculation of a person's height and weight, and is categorized as follows: BMI from 18 to BMI from 25 to BMI from 30 to BMI of 40+ - extremely obese In addition, results from the 2009 analysis of the prevalence of obesity revealed that: Adults were less likely to be obese (20%) or extremely obese (3%) if they had completed a college degree than high school graduates and those with less than a high school degree.
According to a study published in the March 8 issue of the New England Journal of Medicine, a promising new treatment for hypophosphatasia (HHP) - a rare and occasionally fatal bone disorder that can affect infants and young children - has been identified by a team of doctors at Washington University School of Medicine in St. Louis, in collaboration with Shriners Hospital for Children and other institutions. The condition is a rare, inherited disease that affects bones and teeth. It upsets bone metabolism by preventing vital minerals, such as calcium, from depositing in the skeleton. In the study, the researchers reveal that young children with the most severe forms of the condition generally demonstrated significantly improved symptoms at one year of treatment, including: improved motor development increased bone strength improved breathing and some participants managed to walk Lead author of the study, Michael P.
